To all when?. t waa/y concern:

Be it known that I, CHARLES H. ZEssIN, a citizen of the United States of America, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hose- Oouplings, of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to certain new and useful improvements in hose-couplers, and has for its object the provision of novel means whereby two sections of hose may be easily, quickly, and effectually coupled together.

Another object of my invention is the proi vision of novel means whereby when the two sections have been placed together they may be securely locked, suitable construction being provided whereby the lock is protected from all rough usages.

A further object of my invention is the provision of novel means whereby the hose may be securely fastened within the coupler-sections; and a still further object is to provide a hose-coupler which will be extremely simple in construction, strong and durable, comparatively inexpensiveto manufacture, and highly efficient when used.

In describing the .invention in detail reference is had to the accompanying drawings, formingapart of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in whichn Figure 1 is a longitudinal sectional view of my improved hose-coupler. Fig. 2 is an end view of the female member. Fig. 3 is a side elevation of the male member. Fig. 4 is an end View of said member. Fig. 5 is a side elevation of the means employed to secure the hose within the coupler-section, and Fig. 6 is a modified form of securing means.

To put my invention into practice, I provide two members, the male member 1 of which carries the enlarged collar 2, having' a projecting tubular portion 3, formed integral therewith. The end of the said tubular extension is recessed, as indicated at 4, and in which is seated the rubber gasket 5. This member 1 has an aperture 6 formed its entire length, and the other end of the member 1 has an annular recess 7, in which is secured the hose 8. The enlarged collar 2 of the member 1 carries the extending lugs 9, to which are secured the arms 10 of the yoke 11, and the arms 1() are pivoted to the lugs 9 by apin 12, and upon the other end of the pin and upon the inner faces of the lugs i) is mounted the cams 14, as illustrated in Figs. and f1 of the drawings.

The female member 15 comprises atubular portion having a central aperture 1G formed longitudinally therein, said member also carrying an enlarged collar 17, and the one end of the female member 15 recessed, as indicated at 18, forming an annular groove similar to the groove 7 of the male member 1. The other end of the female member carries an annular recess 19, which forms an annular projection 21), which is adapted to be seated in the annular recess L1 of the male member, and upon the outer wall of the annular recess 19 I provide the collar 25, which has notches 21 formed therein diametrically opposite each other, the object of which will be hereinafter described.

In securing the hose within the coupler-sections I employ an annular ring or band, as illustrated in Fig. 5 of the drawings, this ring or band being split, as indicated at 22, the one edge of said band being cut away, as indicated at 23,forming a lug 24C, through which is passed a screw 25, and when the hose has been placed within the annular recesses or grooves 7 and 18 the band is placed in said recesses and the screw 25 adjusted to expand the ring or band, whereby the hose will be forced outwardly against the outer shell 26 of the sections, whereby the same will be rigidly and securely held.

W'hen it is desired to connect two sections of hose together, the female member 15 is forced inwardly until the portion 2O has been seated within the recess L1, the member 15 having first been rotated until the notches 21 are in alinement with the cams 1li, when the same is further forced into position, rotated until the cams 14 have become engaged behind the annular collar 20', when the yoke 11 is forced downwardly toward the hose, the cam 111 forcing the collar 20 against the annular collar 2,

IOD

nular bands, and it will be seen that the hose Y may be removed at any desired time when a new hose is to be placed therein. In Fig. 6 of the drawings I have illustrated a modified form of securing the hose within the couplersections, wherein a wedge 2.7 is employed similar to the annular band or ring.

While I have herein shown and described a practical embodiment of my invention, it will be obvious that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters l Patent, is

member and having extending lugs, said female member comprising a tubular portion having an annular recess formed in its one end, an enlarged collar having notches formed upon said member, a yoke pivoted to the lugs of the male member, cams carried by said yoke and adapted to engage the enlarged collar having notches formed therein.

2. A hose-coupling comprising a male and female member with an aperture formed in each of said members longitudinally thereof, said male member having an annular recess formed in one end thereof, a tubular extension carried by the same end of the member, an annular collar formed integral with said member and having extending lugs, said female member comprising a tubular portion having an annular recess formed in its one end, an enlarged collar having notches formed upon said member, a yoke pivoted to the lugs of the male member, cams carried by said yoke and adapted to engage the enlarged collar having notches formed therein.

In testimony whereof I afx my signature in the presence of two witnesses.

CHARLES H. ZESSIN.
